- Abstract
This paper proposes a new way to reduce the drag of the fluid flow past a external fins pipe. If a little rectangular leaf is suitably installed upstream of the base pipe of the external fins pipe, not only the drag will be reduced, but also the heat transfer will be enhanced in a suitable range of Reynolds number. An experimental investigation showed that compared with a general external fins pipe, the new way can reduce the drag more than 40% and enhance the heat transfer about 10% meanwhile.
